can I print from wireless laptop?

After some trial and error, I finally got my wireless home network up and running last night. I have a desktop PC that is hardwired to the cable modem and printer, a Netgear wireless router, and a Sony laptop setup with a wireless card.

Once I got everything up and running, I was able to share files and drives across the network, but I couldn't figure out how to share the printer, which is currently attached to the desktop PC. Can I print from the wireless laptop to the printer using the desktop as a go-between?
